are connected in adurable relation against liability of detachmentincident to use or wear. V A 'further and importantobject of thisinvention is. the provision of a lawn frake whichfis strong, eflicientto use, practical, and of light weight as to best adapt it for use inconnection with raking of lawns and thelike; In the ordinary la y Inrake 'Whichembodies a tooth structure connected to a sup 1 porting bar"to provide a pair ofteethat oneside of the bar'and a blunt ended U-shaped tooth at the other side'of the bar, the tooth structure is notefiectivelyconnected to the frame, and-in short time the teeth will,work loose. Continual driving of the teeth into place renders the teethineffective for use, as'they become disaligned and in time are so loosethat they will not retain their position in the rake structure. Variousexpedients for retaining teeth have been proposed, and in general usethe teeth are either crimped into a supporting frame or the frame ismutilated into engagement with the tooth. Soldering has also beentried,-but the results are no better. With the improved type of rake thesupporting bar is sectionally formed to receive" the teeth prongs insuch relation thereinfthat the prongs cannot become detached so long asthe sections" of the frame are held together. The rake is reinforced inproper manner, and the structure'takes into consideration the fact thatthe single strands of teeth are; used more than the U-shaped teeth, i

Other objects and advantages ofthis invention will be apparent duringthe course 'of the following detailed descriptionn In the accompanyingdrawing, forminga part of this specification, and. wherein similar'reference characters designate corre sponding parts throughout theseveral views,

which the teeth are formed to cooperate with the frame. i Figure 2 is atransverse cross sectional view taken through therakehead; v

' In "the drawing, wherein for the purpose of illustration is shown onlya preferred embodiment; of this invention the letter may generallydesignatethe, improved rake structure, which may'consist of a series ofthenovel teeth structures B supported upon so 7 a novel. type of frameor supporting bar C A series ofthe tootlrstructuresB are of courseemployed in'connection with the rake, and each of the tooth structures13 consist of a length of wire material, which in the ordinary instanceis number 9 gage annealed steel wire, bent intermediate its ends toprovide a pair of lengthsof material connected by an-arcuate .bight 10.Each one of these lengths of material is bent intermediate its ends toprovide a complete loop 11; the loops 11 extending inwardly towards eachother and lying in thesame planef To one side of the loops 11 a U shapedtooth 12 is provided with the arcuate bight portion 10 at its free end;this tooth being arcuated' from the loops 11 toward its free end. Fromthe loops 11 in the other direction,,a pair "of spaced and substantiallyparallel teeth 13 and let are provided, which are'relatively ate itsends.

Y e he c, whi ay .epie e i t y be called a supporting bar; consists of apair of angle sections 20 and 21. These angle sections each include a--sliort leg-cause a' longer leg 24.

It is ofvery durable construction, and light in weight. This type of rake whichemploys the blunt ended teeth 12 and the single strand teeth 13 and 14isgenerally recognized astlle most eflicient ,forl' u se in connectionwith Ir aking of lawns. The U-shapedblunt teeth '12 are "generall usedin the springtime and in seasonswhen the soil is very loose, so that thegrass can be properly raked without pulling up of the soil. On the otherhand,

in seasons when the, grass is very thick, such as in'late summer o'rfall, the single strand teeth l3 and ,l4 .are used for raking, and
